Answer: We have the following function:

f (x) = x ^ 2

We have the following transformation:

Expansions and horizontal compressions

The graph of y = f (bx):

If 0 <b <1, the graph of y = f (x) expands horizontally by the factor of 1 / b.

Applying the transformation:

y = (0.2x) ^ 2

The factor is:

1 / b = 1 / 0.2 = 5

Answer:

b. expanded horizontally by a factor of 5

Answer:

60 copies

Step-by-step explanation:

first you take 1/6th of the original 90 copies which is 15 and subtract that from the 90, you are left with 75 copies which is how many they had left at the end of yesterday. then you take 1/5th of the 75 copies that are left which is also 15 and you subtract that from 75 and you get 60. that's why at the end of today there are 60 copies left.

Answer:

Step-by-step explanation:

It's hard to tell what you really intend. I'll do it both ways.

Way One

9 + x/6 = 11          Subtract 9 from both sides.

x/6 = 11 - 9

x/6 = 2                 Multiply both sides by 6

x = 2 * 6

x = 12

1 + 3x = 1 + 3*12 = 1 + 36 = 37

Way Two

(9 + x)/6 = 11         Multiply both sides by 6

9 + x = 11 * 6         Simplify the right side

9 + x = 66            Subtract 9

x = 57

1 + 3*57 = 1 + 171 = 172

Answer:

33

Step-by-step explanation:

Use PEMDAS, so the first thing you solve is what's in the parenthesis.

(6 + 1) = 7

(5 -2) = 3

So now your equation looks like 4 + 2 x 7 + 5 x 3

Now multiply the numbers needed

2 x 7 = 14

5 x 3 = 15

So now it looks like 4 + 14 + 15

Simplify

4 + 14 = 18 + 15 = 33

Answer:

33

Step-by-step explanation:

This is the answer because:

You can use PEMDAS or GEMS

PEMDAS: Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction

GEMS: Grouping (Parenthesis), Exponents, Multiplication and Division (whichever one comes first from left to right.), Addition and Subtraction (whichever one comes first from left to right.)

1) First, we have to do grouping (parenthesis)

(6+1) = 7

(5 - 2) = 3

New equation: 4 + 2 x 7 + 5 x 3

2) Next, we have to do multiplication

7 x 2 = 14

5 x 3 = 15

New equation: 4 + 14 + 15

3) Finally, add everything up.

4 + 14 + 15 = 33

Step-by-step explanation:

Answer:

(2x+7)(x-5)=0

2x+7=x-5

2x-x=5-7

X=-2

Answer:

x = -2

Step-by-step explanation:

let the unknown number be x

[tex]9 \times x + 2 = 8 \times x \\ 9x + 2 = 8x[/tex]

Collect like terms and simplify

[tex]9x - 8x = - 2 \\ x = - 2[/tex]

The unknown number would be x = -2.

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

We have given a statement as "The sum of nine times a number, and 2, is equal to eight times the number."

Let the unknown number be x

9x + 2 = 8x

Collect like terms and simplify;

9x - 8x = -2

x = -2

Thus, the variable would be x = -2.

Answer:

[tex]\huge\boxed{\red{\boxed{c)(0,-4)}}}[/tex]

Step-by-step explanation:

to find y-axis of the function we have to take 0 x and calculate it

according to the question:

another way to think about it

the function is a linear function i.e f(x)=mx+b where m is the slope (rate of change) and b is the y-intercept (where a line would cross y-axis)

our given function is f(x)=2x-4

using a little algebra we get

where -4 is y-intercept

hence,

the line of the function would cross y-axis at (0,-4) coordinate

Answer:

51°

Step-by-step explanation:

Remember, all 3 angles must add up to 180°

We can tell that this triangle is a right triangle, or a triangle that has a 90° angle. We also have another angle given, which is 39°. Currently we have two angles given.

Since all 3 angles have to add up to 180°,

90 + 39 + x = 180°

129 + x = 180°

180 - 129 = x

x = 51°

The missing angle is 51°

To see if your calculation is correct, you could add all 3 angles, and it should give you 180 as a sum.

90 + 39 + 51 = 180

Correct!

The answer is choice 2 and 3, that is "The quotient has a final decimal and the whole number is less than 11".

Step-by-step explanation:

The product of a ratio: amount (r) over other(s) (variance from 0) becomes mandatory to note this quotient and in the following case Thus q is = 0.0882352941.

It wasn't a repeating decimal, however a final decimal, so it's got an end.

Its quotient may be less than 11 in total.

Answer:

4t(t+3), 5k²(2k-3), 4x²(2x-5), t=0 and t=1/3, y=0 and y=-2, n=0 and n=-7/4

Step-by-step explanation:

To factor these, we can factor out a constant and/or variable. For number 12, these terms have 4t in common (you can divide any term in the expression by 4t and have no remainder), so we can pull that out. This makes 4t(t+3) because if you distributed, you would end up with the same answer. The answer for 12 is 4t(t+3).

For 13, we do the same thing, except with 5k². When we pull this out of the equation, we end up with 5k²(2k-3), which is the factored expression.

For 14, we can take out 4x². This becomes 4x²(2x-5), the factored expression.

For 15, we actually have to solve, so we can take out a t. This is t(3t-1)=0. We can set both terms (one outside the parentheses and the other one inside the parentheses) equal to zero to solve. t=0, 3t-1=0. To solve the second equation for t, you use inverse operations and end up with t=1/3. The answers are 0 and 1/3.

For 16, we have to solve as well, so take out a 5y. 5y(y+2)=0. Solve for y again. 5y=0, y+2=0. y=0, y=-2 are the answers.

For 17, take out a 3n. 3n(7+4n)=0. Solve for n. 3n=0, 7+4n=0. n=0, n=-7/4 are the answers.
